The first pictures have surfaced of the 29-year-old man accused of Saturday’s stabbing in a London underground station. Some of the photos showed the suspect, identified as Muhaydin Mire, facing police at the Leytonstone subway station and a large pool of blood on the floor as terrified commuters flee the scene.

Mire appeared in custody Monday morning at Westminster Magistrates' Court accused of attempted murder of a 56-year-old man, who was seriously wounded in the attack. The suspect, wielding a knife, apparently entered the Leytonstone subway in east London Saturday night around 7 p.m. local time where he reportedly shouted, “This is for Syria” and “All your blood will be spilled,” and allegedly stabbed three people, according to British newspaper the Independent

British police are ramping up patrols at transport hubs across London to “identify and deter terrorism” following the knife attack, the Associated Press reported. The incident happened days after Parliament approved British airstrikes against targets of the Islamic State group in Syria. U.K. Prime Minister David Cameron has said the airstrikes will not increase the likelihood of an attack on Britain, which is on its second-highest security alert level of “severe,” Reuters reported.

A video posted to YouTube later showed a man in the station yelling, “You ain’t no Muslim, bruv,” at the alleged attacker as he was being arrested by police. The phrase, using slang for “brother,” has become a trending hashtag on social media.

"#YouAintNoMuslimBruv, just another psychopath attempting to use religion as an excuse to justify your barbaric actions!!" said one Twitter user, Natasha.

Cameron reportedly used the phrase in a speech during a press conference Monday, saying it "summed it all up."

"Some of us have dedicated speeches and media appearances and soundbites and everything to this subject," the U.K. prime minister said, according to Daily Mirror. "But 'you ain't no Muslim, bruv' said it all much better than I ever could."
